Can fuel-reduction treatments really increase forest carbon storage in the western US by reducing future fire emissions?

Creator:: Campbell, John L., Harmon, Mark E., and Mitchell, Stephen R.
Abstract:: It has been suggested that thinning trees and other fuel-reduction practices aimed at reducing the probability of high-severity forest fire are consistent with efforts to keep carbon (C) sequestered in terrestrial pools, and that such practices should therefore be rewarded rather than penalized in C-accounting schemes. By evaluating how fuel...

Observations and assessment of forest carbon dynamics following disturbance in North America

Creator:: Goetz, S. J., Bond-Lamberty, B., Law, B. E., Hicke, J. A., Huang, C., Houghton, R. A., McNulty, S., O'Halloran, T., Harmon, M., Meddens, A. J. H., Pfeifer, E. M., Mildrexler, D., and Kasischke, E. S.
Abstract:: Disturbance processes of various types substantially modify ecosystem carbon dynamics both temporally and spatially, and constitute a fundamental part of larger landscape-level dynamics. Forests typically lose carbon for several years to several decades following severe disturbance, but our understanding of the duration and dynamics of post-disturbance forest carbon fluxes remains...

Contributions of ectomycorrhizal fungal mats to forest soil respiration

Creator:: Phillips, C. L., Kluber, L. A., Martin, J. P., Caldwell, B. A., and Bond, B. J.
Abstract:: Distinct aggregations of fungal hyphae and rhizomorphs, or "mats", formed by some genera of ectomycorrhizal (EcM) fungi are common features of soils in coniferous forests of the Pacific Northwest. We measured in situ respiration rates of Piloderma mats and neighboring non-mat soils in an old-growth Douglas-fir forest in western Oregon...

Burning the legacy? Influence of wildfire reburn on dead wood dynamics in a temperate conifer forest

Creator:: Donato, Daniel C., Fontaine, Joseph B., and Campbell, John L.
Abstract:: Dynamics of dead wood, a key component of forest structure, are not well described for mixed-severity fire regimes with widely varying fire intervals. A prominent form of such variation is when two stand-replacing fires occur in rapid succession, commonly termed an early-seral “reburn.” These events are thought to strongly influence...

Detecting landscape changes in the interior of British Columbia from 1975 to 1992 using satellite imagery

Creator:: Sachs, Donald L., Sollins, Phillip, and Cohen, Warren B.
Abstract:: To consider the regional scale effects of forest management requires complete and consistent data over large areas. We used Landsat Thematic Mapper and Multispectral Scanner (TM and MSS) imagery to map forest cover and detect major disturbances between 1975 and 1992 for a 4.2 x 106 ha area of interior...

Assessing the Carbon Consequences of Western Juniper (Juniperus occidentalis) Encroachment Across Oregon, USA

Creator:: Campbell, John L., Kennedy, Robert E., Cohen, Warren B., and Miller, Richard F.
Abstract:: Our ability to assess the continental impacts of woody encroachment remains compromised by the paucity of studies quantifying regional encroachment rates. This knowledge gap is especially apparent when it comes to quantifying the impact of woody encroachment on large-scale carbon dynamics. In this study, we use a combination of aerial...

Fuelwood characteristics of northwestern conifers and hardwoods

Creator:: Wilson, Pamela L., Funck, James W., Avery, Robert B., and Oregon State University. Forest Research Laboratory
Abstract:: This publication collates the published ranges of fuelwood characteristics for 33 conifer and 20 hardwood species in the Pacific Northwest. The following characteristics are covered: specific gravity, percent moisture content, higher heating value, and percent ash of wood and bark; percent bark by volume; and ultimate analysis (percent carbon, hydrogen,...

Influence of forest structure and experimental green-tree retention on northern flying squirrel (Glaucomys sabrinus) abundance

Creator:: Holloway, Gillian L., Smith, Winston P., Halpern, Charles B., Gitzen, Robert A., Maguire, Christine C., and West, Stephen D.
Abstract:: In many regions of the world, forest management has shifted from practices emphasizing timber production to more sustainable harvesting that integrates ecological values, including maintenance of biodiversity, wildlife habitat, and ecological goods and services. To this end, management strategies emphasize retention of stand structures that meet the needs of forest-obligate...

Conifer DBMagic: a database housing multiple de novo transcriptome assemblies for 12 diverse conifer species

Creator:: Lorenz, W. Walter, Ayyampalayam, Savavanaraj, Bordeaux, John M., Howe, Glenn T., Jermstad, Kathleen D., Neale, David B., Rogers, Deborah L., and Dean, Jeffrey F. D.
Abstract:: Conifers comprise an ancient and widespread plant lineage of enormous commercial and ecological value. However, compared to model woody angiosperms, such as Populus and Eucalyptus, our understanding of conifers remains quite limited at a genomic level. Large genome sizes (10,000–40,000 Mbp) and large amounts of repetitive DNA have limited efforts...

Trends in stream nitrogen concentrations for forested reference catchments across the USA

Creator:: Argerich, A., Johnson, S. L., Sebestyen, S. D., Rhoades, C. C., Greathouse, E., Knoepp, J. D., Adams, M. B., Likens, G. E., Campbell, J. L., McDowell, W. H., Scatena, F. N., and Ice, G. G.
Abstract:: To examine whether stream nitrogen concentrations in forested reference catchments have changed over time and if patterns were consistent across the USA, we synthesized up to 44 yr of data collected from 22 catchments at seven USDA Forest Service Experimental Forests. Trends in stream nitrogen presented high spatial variability both...
